Features

When subjected to both pressure and vacuum, Saunders® industrial diaphragm valves operate and close 100% leak-tight. This feature reduces processing and handling costs by cutting out the waste normally associated with conventional valve designs.

Available in both weir and straight through designs and with a number of lining options to suit both aggressive and abrasive line service

When manual operation is inadequate or inconvenient, Saunders offer a variety of actuators covering valve sizes up to DN250, for different line and operating pressure options. We offer three different actuators, designed for various characteristic performances.

Benefits

  • Corrosion resistance
  • Abrasion resistance
  • Leak tight* – on pressure and vacuum services, valves operate and close *100% leak tight in accordance with standards MSS SP-88 and BS EN 12266-1, even after thousands of operations, reducing processing and handling costs, by eliminating emissions normally associated with other valve designs.
  • Easy maintenance
  • Operating mechanism no in contact with line media
  • Suitable for control – Throttling and control characteristics are enhanced by a streamlined flow path that is cavity free and provides excellent flow control capabilities.
  • Cost effective
  • Valve usable in any position self drain – The Saunders valve can be installed in any position without affecting its operation. However, we recommend installation to be at least 6 times the pipe diameter from bend or pump (10 times the pipe diameter if the valve is used for control).
